Question

I need to find a way to programmatically zoom out of a WebView on android. Background: I created a phonegap/cordova web app which has a fixed layout. I am using these settings to proper display of the app across devices:

this.appView.getSettings().setUseWideViewPort(true); 
this.appView.getSettings().setLoadWithOverviewMode(true);
this.appView.getSettings().setSupportZoom(true);
this.appView.getSettings().setDefaultZoom(ZoomDensity.FAR);
this.appView.getSettings().setBuiltInZoomControls(true);
this.appView.setInitialScale(0);

So far it worked well until a text input field gains focus. Then the app gets rescaled and its impossible to return to the proper view. I searched and worked on this problem for over a day now tried many possible solutions but none worked for me. The approach I am working now on is to make a native call when the text input field looses focus and then to reset the zoom. But I don’t know a way to reset the zoom.

webView.zoomOut(); is too slow and webView.setInitialScale(..); does nothing.

I am looking for something like webView.setZoomLevel(..); or webView.setScale(..); but I can not find it in the api.

Pulling out my hair about this.. Please help.

BTW, my meta viewport setting is

<meta name="viewport" content="width=640,height=device-height,target-densityDpi=device-dpi" />

No answer for this question. I guess there is just no way to set the zoom level other than zooming out using the zoomOut() function. So I had to live with that.
